Description

TECHNICAL FIELD [0001] The present invention relates to a sunroof device including a blind unit,

The present invention relates to a sunroof device, and more particularly, to a sunroof device including a blind unit having a plurality of blind members that are individually driven to receive a driving force generated from a driving source.

Due to the recent upgrading of vehicles and diversification of customers' preferences, the spread of vehicles equipped with sunroofs is becoming active. The sunroof is a kind of auxiliary window frame mounted on the roof of the vehicle to assist in driving comfort, such as internal ventilation of the vehicle and open feeling. The sunroof is designed to have a strength higher than a predetermined standard to protect the interior of the vehicle from the outside, and to block ultraviolet rays and infrared rays. Accordingly, it is common that the sunroof is provided with a sunroof member made of a glass material and a roll-blind, which is a sunshade which is an ornamental shade for further blocking ultraviolet and infrared rays.

On the other hand, in recent years, a panorama sunroof (panorama sunroof) has been provided which provides a wide open area to enhance the open feeling. Such a panoramic sunroof device is generally equipped with a pair of sunroofs and a pair of roll-blinds, the open area being controlled by the user.

However, the pair of blinds are independently connected to the independent pair of motors, respectively. Accordingly, there is a problem that not only a space for installing a motor for a pair of roll-blind drives but also a troublesome operation of operating a pair of roll-blinds is troublesome. Due to such a problem, various studies for improving the driving operability of a pair of roll-blinds applied to a panoramic sunroof have been continuously carried out in recent years.

The second movable pins 45, 55 are moved along the first and second control rails 60,

Specifically, the first movable pin 45 moves out of the first confining section 61 of the first control rail 60 and is moved to the first non-confining section 65 via the first open section 64 The first interfering body 42 is rotated about the first connecting pin 41a as a center axis due to the compressive force of the first rotating direction elastic member 44 so that the first connecting member 22 is not restrained.

The second movable pin 55 moves only through the second restraint section 71 of the second control rail 70, which is relatively longer than the first restraint section 61 of the first control rail 60 , And the second control member (50) continues to restrain the second linking member (23).

4C, the first movable pin 45 is moved to the first closed section 66 of the first control rail 60 so that the first control member 45 40 again restrains the first connecting member 22. At this time, the first interfering body 42 of the first control member 40 is urged toward the paper supporting member 41 by the restoring force of the compressed elastic force of the first rotation direction elastic member 44 and is elastically pressed, The rotation is guided.

The second movable pin 55 sequentially passes through the second open section 74 and the second unconstrained section 75 of the second rotation section 72 of the second control rail 70, 2 control member 50 unrestricts the second linking member 23. At this time, the second interfering body 52 is rotated about the second connecting pin 51a by the compression force of the second rotating direction elastic member 54, thereby restricting the second connecting member 23 do.

4D, the first movable pin 45 is moved to the auxiliary section 67 of the first control rail 60, and at the same time, The pin 55 is finally moved to the second closed section 76 of the second control rail 70. As the second movable pin 55 is moved to the second closed section 76, the compressive force of the second rotating direction elastic member 54 is restored, so that the second interfering body 52 is rotated to the initial position.

Through the steps of Figs. 4A, 4B, 4C and 4D as described above, the first and second blind members 11 and 12 completely close the opening (not shown) of the vehicle.

4E, when the driving force of the driving source 21 is reversed, the first and second connecting members 22 and 23 are moved from the first and second guide members 24 and 25, Is moved in the opening direction (O1) (O2) in conjunction with the driving force. The first and second control members 40 and 50 in a state in which the first and second connecting members 22 and 23 are constrained are respectively connected to the first and second control rails 60 and 70, After sequentially passing through the first and second restoration sections 63 and 73 and the first and second restraint sections 61 and 71 of the first and second driving sections 26a and 26b . The first and second driving pins 22a and 23a protruding from the first and second connecting members 22 and 23 are also inserted into the first and second driving areas 26a and 26b The first and second blind members 11 and 12 connected to the first and second connecting members 22 and 23 are moved in the opening direction O1 to O2 to open the vehicle Lt; / RTI >

5A to 5D show a state in which only the first blind member 11 among the first and second blind members 11 and 12 of the blind unit 10 is driven in an independent driving phase in which an opening (not shown) Operations are sequentially shown.

5A shows a standby state in which the first and second connecting members 22 and 23 are restrained by the first and second control members 40 and 50 to wait for transmission of the driving force. 5A is the same as the standby state shown in FIG. 4A, and thus a detailed description thereof will be omitted.

5B, the driving source 21 rotates in the forward direction, so that the first and second connecting members 22 and 23 (first and second connecting members 22 and 23) are driven by the driving forces in the C1 and C2 directions transmitted by the first and second guide members 24 and 25 Are driven in the closing directions C1 and C2, respectively. The first and second control members 40 and 50 connected to the first and second connecting members 22 and 23 are also driven in the C1 and C2 directions together with the first and second movable pins 22 and 23. In addition, (45) and (55) are moved along the first and second control rails (60) and (70).

Specifically, the first movable pin 45 is moved out of the first confining section 61 of the first control rail 60 and passes through the first open section 64 of the first rotation section 62, The first interfering body 42 is rotated from the first supporting body 41 to unrestrict the first connecting member 22 by moving to the restraining section 65. [ At the same time, the second movable pin 55 passes through the second constraint section 71, which is relatively longer than the first constraint section 61 of the first control rail 60, The second connecting member 23 is continuously restrained.

Accordingly, the first blind member 11 connected to the first linking member 22 is also moved in the direction of O1 to open the opening (not shown) of the vehicle.

At the same time, the second linking member 23 is constrained to the second control member 50, so that the second guide member 25 connected to the driving source 21 interlocks with the O2 direction driving force, Is moved away from the second guide groove (25a) of the member (23) and separated in the O2 direction. Therefore, the second blind member 12 connected to the second linking member 23 is not driven and maintains the posture in which the opening (not shown) of the vehicle is kept closed. At this time, the second linking member 23 is interfered with the second height direction elastic member 90 so as to be elastically pressed, so that the second guide member 25 does not interlock with the movement in the O2 direction.

On the other hand, when the driving force of the driving source 21 is again switched to the forward direction, the first and second guide members 24 and 25 are moved again in the closing direction in the C1 and C2 directions. The first linking member 22 connected to the first guide member 24 is moved in the C1 direction to move the first blind member 11 which has opened the opening of the vehicle (not shown) in the closing direction do. In addition, the second guide member 25 separated from the second linking member 23 moves in the C2 direction, and is returned to a position connected to the second linking member 23 again. That is, the first and second connecting members 22, 23 and the first and second guide members 24, 25 are returned to the state shown in FIG. 5B.

5B, the first and second guide members 24 and 25 continue to be moved in the C1 and C2 directions continuously by the forward driving force of the driving source 21. As a result, as shown in FIG. 5D, The member 22 passes through the auxiliary section 67 of the first control rail 60 and the second connecting member 23 passes through the second closing section 76 of the second control rail 70, (23) is restrained by the second control member (50). At this time, the second interfering body 52 of the second control member 50 is interlocked with the restoring force of the compression force of the second rotation direction elastic member 54.

The driving force of the driving source 21 is reversed so that the first and second control members 40 and 50 in a state of restricting the first and second connecting members 22 and 23 The first and second return rails 60 and 70 pass the first and second return sections 63 and 73 to return to the standby position as shown in FIG. The first and second movable fins 45 and 55 protruding from the first and second interferometers 42 and 52 may compress the first and second elastic members 46 and 56, So as to pass through the first and second return sections 63 and 73 having relatively small insertion depths.

Figs. 6A to 6D sequentially show the driving operation of the independent driving step in which only the second blind member 12 opens the opening (not shown) of the vehicle.

The first and second link members 22 and 23 are restrained by the first and second control members 40 and 50 to wait for the transmission of driving force as shown in FIG. 21 is transmitted. Then, by the driving forces in the C1 and C2 directions transmitted from the first and second guide members 24 and 25, the first and second connecting members 22 and 23, which are in a state of restricting the first and second connecting members 22 and 23, The control members 40 and 50 are driven in the C1 and C2 directions. At this time, the forward rotation driving time of the driving source 21 shown in FIG. 6B is longer than that of FIG. 5B.

Accordingly, the first movable pin 45 is moved out of the first confining section 61 of the first control rail 60 and moved in the first open section 64 of the first rotation section 62 and the first open section 64 of the first non- (65), and then moves to the first closed section (66). Therefore, the first control member (40) restrains the first connecting member (22) after unconstrained. Here, the elastic force of the first rotation direction elastic member 44, which has been compressed by the first movable pin 45 passing through the first opening section 64, is returned again, The interfering body 42 is rotated to the initial position toward the first support body 41.

At the same time, the second movable pin 55 passes through the second constraint section 71, which is relatively longer than the first constraint section 61 of the first control rail 60, And passes through the second open section 75 and is located in the second unconstrained section 75. Thereby, the second interfering body 52 of the second control member 50 is separated from the first supporting body 41 and rotated, thereby unrestraining and separating the second connecting member 23. At this time, the elastic force of the second rotation direction elastic member 54 is compressed by the rotation of the second interfering body 52.

The rotation of the driving source 21 is reversed so that the first guide member 24 is separated from the first linking member 22 constrained to the first control member 40 to be separated from the first linking member 22 in the opening direction O1 direction. At this time, since the first linking member 22 is elastically pressed by the first height direction elastic member 80, the first blind member 11 connected to the first linking member 22 is not driven (Not shown) of the vehicle.

The second connecting member 23 unreeleved from the second control member 50 is rotated in the O2 direction in the opening direction in association with the driving force transmitted by the second guide member 25 by the reverse rotation of the driving source 21 . As a result, the second blind member 12 connected to the second linking member 23 is also moved in the O2 direction to open the opening (not shown) of the vehicle. At this time, the second movable pin (55) of the second control member (50), the second drive pin (23a) of the second linking member (23) and the second support body (51) Movement is guided along the second drive region 26a of the rail 26. [

On the other hand, when the direction of the driving source 21 is changed again to the normal direction, the first and second guide members 24 and 25 are moved in the closing direction in the direction of C1 and C2 again. The second connecting member 23 connected to the second guide member 25 is moved in the C2 direction to move the second blind member 12 which has opened the opening of the vehicle (not shown) in the closing direction . In addition, the first guide member 24 separated from the first linking member 22 moves in the C1 direction, and is returned to the position where it is connected to the first linking member 22 again. That is, the first and second connecting members 22, 23 and the first and second guide members 24, 25 are returned to the state shown in FIG. 6B.

The first and second guide members 24 and 25 are continuously moved in the C1 and C2 directions by the forward driving force of the driving source 21 in the state of being returned as shown in FIG. The second connecting members 22 and 23 are restored to the state in which they are both restrained by the first and second control members 40 and 50. The driving force of the driving source 21 is reversed so that the first and second control members 40 and 50 in a state of restricting the first and second connecting members 22 and 23 And then returns to the standby position as shown in FIG. 6A by passing through the first and second return sections 63 and 73 of the first and second control rails 60 and 70.

For reference, in order for any one of the first and second blind members 11 and 12 to independently open or close the opening (not shown) of the vehicle, the first and second blind members 11 and 12, Only one of them is driven at a position where the opening (not shown) of the vehicle is completely opened or closed at the same time.
